Apple M1 chipset-based MacBooks are now available for purchase in select markets. It’s a radical change from the previous generation MacBooks but you won’t see it on the surface because it’s internal. The M1 chip replaces the Intel chipset that Apple claims is revolutionary in the PC world. Most reviews point out that the M1 chip holds up to these claims, in fact, it pushes the boundaries on how fast a laptop can go. It becomes even more fascinating to know, thanks to the latest revelations from iFixit people who have performed complete teardowns of the latest MacBook Air and MacBook Pro.
In their respective teardowns, one of the main points of the MacBook Air and MacBook Pro was that they aren’t very different from each other. Obviously, the biggest difference between the two MacBook models is the fan that the Pro has but the Air lacks. And that difference has more to do with performance than with the size and footprint of these MacBooks. According to iFixit, the fan was replaced by an aluminum heatsink that hangs from the logic board to dissipate the heat generated by the processor.
iFixit noted that this system works perfectly for the MacBook Air but, in turn, introduced the performance cap which is something the MacBook Pro can push through because it has a fan. “Not much to do here. A thick cold plate on top of the M1 processor draws heat through conduction to its flatter, cooler end, where it can safely radiate. Without a fan, this solution may take longer to cool down and may finish sooner, but by avoiding heat pipes or a vapor chamber, the heatsink also has more mass to saturate with thermal energy. There are no moving parts and nothing to break. You’ll want a new thermal paste from time to time, and that’s it, ”iFixit noted in its teardown report for the MacBook Air.
The MacBook Air is also slightly different from its Intel-based predecessors. The battery is different in size from its previous counterpart, along with the placement of a few other components. But the overall repair process for the M1 powered MacBook Air will remain “almost totally unchanged”. This means that the MacBook Air will be repaired using the same method Apple engineers used for Intel-based MacBooks. Apple is also likely to charge the same repair fee as it does for Intel-based MacBooks, in case the warranty has expired.
The MacBook Pro, on the other hand, has the privilege of having the fan cool inside for when they get hot while handling heavy workloads. The fan, however, is no different from the one equipped inside the predecessor. It has been speculated that the MacBook Pro’s fan will be quieter than the previous model, but that’s not the case.
According to iFixit, “The single fan of the M1 MacBook Pro is identical to the fan of the two-port Intel MacBook Pro we purchased earlier this year. Not similar, identical. “But while that is true, the fan has some dampened noise and this is because the Apple M1 chipset can handle maximum workloads without generating a lot of heat.” Remember, this same M1 chip works. fine in the fanless MacBook Air, so this fan probably doesn’t have much to do even under prolonged load. “
The superstar, the M1 chip, looks like the way Apple showcased it in several promotional materials. It is a 5-nanometer processor that features an 8-core design, four of which are reserved for high-performance cores and four for efficiency cores. The memory chips used with the M1 chip are similar to those in recent iPad models. “If it looks familiar to you, it might be because you saw one of our recent iPad teardowns. Unsurprisingly, Apple copied some of its tasks here. By putting the RAM into the M1 package, every part of M1 (CPU, GPU, Neural Engine, etc.) It can access the same memory pool without having to copy or cache data in more than one place, “iFixit noted in its disassembly.
But while a lot of things are great, Apple hasn’t made these memory modules user accessible. This means that they will be replaced together with the processor and cannot be extracted from the complete module. But this is something Apple could fix in the future. This is Apple’s first generation of ARM-based chipsets. The move from Intel to M1 will take about two years and that’s a lot for Apple to address a few things that could be in its favor.
Apple recently launched its own ARM-based M1 chipset that powers the MacBook Air and MacBook Pro.
- Apple’s MacBook Air and MacBook Pro are no different from the inside.
- The MacBook Air doesn’t have a fan inside, but the Pro does.
- The M1 chipset has a memory module similar to that of the iPad.
